The rest parameter is an ES6 syntax that is used to represent an indefinite number of elements as an array.
Example
function add(...elements){
let sum = 0;
for(let i of elements){
sum +=i;
}
console.log(sum);
}
console.log(add(2,4,6)); //12It can also be used to get the rest elements of an array.
Example
let snacks = ["meatpie", "sausage", biscuit", "pizza"];
let drinks = ["Coke", "Sprite", "Malt", "Fanta"];
snacks.push(...drinks);
console.log(snacks); //combines all elements of snacks and //drinksAuthor
